Hard-Disk Drive Sequence; Boot Sequence - Dell OptiPlex E1 Reference And Installation Manual

To set the drive-type number in the System Setup program, highlight the appropriate
drive category (Primary Drive 0 or Primary Drive 1) and type the correct drive-type
number. If you prefer, you can press the right- or left-arrow key to increase or
decrease, respectively, the drive-type number until the correct one is displayed.
The Drive 0 and Drive 1 categories display the following five parameters for each drive:
Drive Type is the drive-type number for the selected hard-disk drive.
Capacity (automatically calculated by the system) indicates the number of mil-
lions of bytes of storage provided by the drive.
Cylinders is the number of logical cylinders.
Heads indicates the number of logical heads in the drive.
Sectors is the number of logical sectors per track.
If none of the supported drive types match the parameters of your new drive, you can
enter your own parameters. To do so, highlight the Drive 0 category and type u to dis-
play User 1. You can then use the right- or left-arrow key to switch between the User 1
and User 2 settings (only two user-defined drive types are allowed). Then press the
<Tab> key to highlight each of the parameter fields in succession, and enter the
appropriate number for each field.
NOTE: The User 1 and User 2 drive types can be used for both the Primary and Sec-
ondary Drive 0 and Drive 1 categories. However, if you select the User 1 or User 2
drive type, you may not obtain optimum hard-disk drive performance. Also, the User 1
and User 2 drive types cannot be used for hard-disk drives greater than
528 megabytes (MB) in capacity.
The Hard-disk Drive Sequence lists installed adapter cards and devices in the order
they will be initialized. The first hard-disk drive in the list becomes the bootable
drive C.
Boot Sequence enables you to set the order of the devices from which the system
attempts to boot.
The term boot refers to the system's start-up procedure. When turned on, the
system "bootstraps" itself into an operational state by loading into memory a
small program, which in turn loads the necessary operating system. Boot
Sequence tells the system where to look for the files that it needs to load.
To set the boot device order, press <Enter> to access the field's pop-up options
menu. Use the up- and down-arrow keys to move through the list of devices. Press
<Enter> to enable or disable a device (enabled devices appear with a check mark).
Press <+> or <-> to move a selected device up and down the list. The following sec-
tions detail typical devices.
